Working Load Limit

Uniform Load Method of Rating BS EN 818-4
All general purpose slings should be rated by the uniform load method as shown in the table below.

7mm	1.5 tonne	2.1 tonne	1.5 tonne	3.1 tonne	2.2 tonne
8mm	2.0 tonne	2.8 tonne	2.0 tonne	4.2 tonne	3.0 tonne
10mm	3.15 tonne	4.25 tonne	3.15 tonne	6.7 tonne	4.75 tonne
13mm	5.3 tonne	7.5 tonne	5.3 tonne	11.2 tonne	8.0 tonne

26mm	21.2 tonne	30.0 tonne	21.2 tonne	45.0 tonne	31.5 tonne
32mm	31.5 tonne	45.0 tonne	31.5 tonne	67.0 tonne	47.5 tonne

Chain Fittings / Terminations

Single Leg, 2 Leg, 3 Leg and 4 Leg Lifting Slings are available with various fittings, the more common of which we offer as standard.

Yoke Clevis Sling Hook,Type 8-043, Grade 8

Yoke Clevis Self Locking Hook, Type 8-026, Grade 8

Yoke Eye Grab Hook, Type 8-041, Grade 8

Yoke Half-Link Shortening Clutch, Type 8-078, Grade 8

Note: The chain fittings shown above are the more popular hooks and leg length adjusters types. Chain sling assemblies can be supplied with alternative fittings in Grade 8, Grade 10 or Grade 12 to suit your requirements.

Examples of alternate chain fittings

• C-Hooks
• Swivel Hooks
• Eye Hooks
• Foundry Hooks
• Clevis Shackles
• Reevable Egg Links

If it is the case that you are needing a more bespoke or special or uncommon chain sling arrangement, then please contact us with your requirements (e.g. number of legs, capacity, fittings required and length etc.) for more information.

Chain Sling Selection

In this catalogue the maximum working load limit for each size of chain is shown. These ratings are based on ideal conditions, however in practice, working conditions may vary widely. All lifting applications should be assessed by a competent person in order to establish the size and type of sling required.

Angle Tensions

In the case of multi-leg slings, the angle between the legs is critical. The actual tension on each leg increases when the angle between the legs increases as shown in the diagram opposite. For this reason all general purpose EN818 lifting chain slings are given a rating based upon use at 90º inc. angle. The included angle between the legs should never exceed 120º.

Chain Sling Headroom

The distance between the crane hook and the load is known as the “Head Room”. If a specific head room is required, the “Reach” of the chain sling must increase as the angle between the legs increases as shown opposite.

Lifting Reach - Effective Working Length

Also know as bearing to bearing (b-b) or chain length.

The reach of a chain sling is the distance between bearing points of the upper and lower terminal fittings. This distance, commonly known as the “Bearing to Bearing” length or effective working length. It is generally not the physical chain length between components, so this should be taken in to consideration when ordering chain slings.

Shortening clutches or grab hooks can also be fitted to a sling assembly to make the chain sling's effective working length adjustable, thus increasing the versatility of the sling.

Unusual Applications

Recommended Load Factors for unusual slinging methods and conditions.
Factor normally applied to W.L.L. of a Single Chain.

Temperature loadings: Applicable to chain temperature

• -40º to 200º C 1
• 200º C to 300º C 0,9
• 300º C to 400º C 0,75

Edge loadings: Applicable to load lifting and load lashing

r = more than 2 x chain size
Load factor 1 (100% WLL)

r = more than chain size
Load factor 0,7 (70% of WLL)

Not recommended without corner protection
